Scientific Literature

Evidence-Based Research

Key peer-reviewed studies supporting HBOT applications across clinical specialties and longevity medicine, with evidence levels and direct links to source publications.

Evidence Levels:

Level I — Systematic reviews, meta-analyses, RCTs Level II — Prospective cohort, clinical studies Level III — Retrospective, case series
1
Level II Prospective Clinical Study

Hyperbaric oxygen therapy increases telomere length and decreases immunosenescence in isolated blood cells

Hachmo Y, Hadanny A, Abu Hamed R, et al. · Aging (Albany NY) · 2020

Key Finding

60 HBOT sessions increased PBMC telomere length by >20% and significantly reduced senescent T-cells — first human evidence of non-pharmacological telomere lengthening.

2
Level I Randomized Controlled Trial

Cognitive enhancement of healthy older adults using hyperbaric oxygen: a randomized controlled trial

Hadanny A, Daniel-Kotovsky M, Suzin G, et al. · Aging (Albany NY) · 2020

Key Finding

HBOT induced significant cognitive enhancements in healthy aging adults via mechanisms involving regional changes in cerebral blood flow.

3
Level I (Review) Comprehensive Review

Hyperbaric oxygen therapy for healthy aging: From mechanisms to therapeutics

Fu Q, Duan R, Sun Y, Li Q. · Redox Biology · 2022

Key Finding

First comprehensive overview of HBOT in aging and geriatric research. Therapeutic targets of HBOT overlap considerably with hallmarks of aging.

4
Level I Randomized Controlled Trial

Physical enhancement of older adults using hyperbaric oxygen: a randomized controlled trial

Hadanny A, Sasson E, Copel L, et al. · BMC Geriatrics · 2024

Key Finding

HBOT improved maximal physical performance and cardiac perfusion in sedentary older adults, including enhanced VO2 max and cardiovascular function.

5
Level I (Meta-Analysis) Systematic Review & Meta-Analysis

Hyperbaric oxygen therapy in inflammatory bowel disease: a systematic review and meta-analysis

Singh AK, Jha DK, Jena A, et al. · European Journal of Gastroenterology & Hepatology · 2021

Key Finding

HBOT achieved response rates exceeding 80% in both ulcerative colitis and Crohn's disease, with significant mucosal healing demonstrated.

6
Level II Clinical Trial Review

Hyperbaric oxygen: B-level evidence in mild traumatic brain injury clinical trials

Figueroa XA, Wright JK. · Neurology · 2016

Key Finding

B-level evidence supporting HBOT for mild TBI and post-concussion syndrome, showing improvements in neurocognitive deficits and post-concussion symptoms.

7
Level II Prospective Clinical Study

HBOT improves symptoms, brain microstructure and functionality in veterans with treatment-resistant PTSD

Doenyas-Barak K, Catalogna M, Kutz I, et al. · PLoS One · 2022

Key Finding

HBOT significantly improved PTSD checklist scores and demonstrated measurable improvements in brain microstructure on advanced MRI in treatment-resistant PTSD veterans.

8
Level I (Meta-Analysis) Systematic Review & Meta-Analysis

Effects of pre-, post- and intra-exercise HBOT on performance and recovery: systematic review and meta-analysis

Huang X, Wang R, Zhang Z, et al. · Frontiers in Physiology · 2021

Key Finding

First meta-analysis on HBOT for exercise performance and recovery. Consistent benefits in muscle recovery, reduced inflammation, and enhanced endurance capacity.

Evidence Summary

The references cited on this site include randomised controlled trials, systematic reviews and meta-analyses, alongside clinical reviews, observational studies and a small number of preclinical studies. Evidence is most established for the UHMS-approved indications; for longevity and cognitive applications it is emerging, comes largely from a single research group, and awaits independent replication.
